Heated liquid PTC, in the absence of a liquid, it will not be damaged. Product terminal where the temperature is below 260C, the use of PTC heating has a great advantage.

Notice: this element CAN NOT be directly put in liquid, it should be isolated with the liquid when it heats it, a shell is needed, the power is reference value. The batter the dissipation is, the bigger the power is. This model can be used without extra dissipation.
